# Control flow & composition nodes

> Branch, merge, time, and compose pipelines and agents.

Add these nodes with the pipeline builder: `pipeline.add(name="...").<node>(...)`. Each entry lists the node's configuration parameters. See the [Pipeline reference](/sdk/pipeline/reference) for `add`, `run`, and lifecycle methods.

## `add_node`

Add a new node to the conversation.

<CodeGroup>
  ```python Sync theme={"languages":{}}
  pipeline.add(name="node").add_node()
  ```
</CodeGroup>

## `agent`

Agent

<Info>Platform docs: [Dynamic node: inputs/outputs determined at runtime.](/nodes/agent/overview)</Info>

<CodeGroup>
  ```python Sync theme={"languages":{}}
  pipeline.add(name="node").agent(use_existing_agent=True, agent=...)
  ```
</CodeGroup>

**Parameters**

<ParamField path="use_existing_agent" type="bool" required />

<ParamField path="agent" type="AcceptsAgent" required />

<ParamField path="model" type="str" default="'gpt-5.4'" />

<ParamField path="agent_config" type="Any" default="{}" />

<ParamField path="processed_inputs" type="dict" default="{}" />

<ParamField path="processed_outputs" type="dict" default="{}" />

<ParamField path="provider" type="str" default="'openai'" />

## `code_execution`

Execute code in the language of your choice.

<Info>Platform docs: [Execute code in the language of your choice.](/nodes/code/overview)</Info>

<CodeGroup>
  ```python Sync theme={"languages":{}}
  pipeline.add(name="node").code_execution(code="...")
  ```
</CodeGroup>

**Parameters**

<ParamField path="code" type="str" required />

<ParamField path="function_name" type="str" default="'main'" />

<ParamField path="input_schema" type="ListType | list[NameTypeValueAny]" default="[]" />

<ParamField path="language" type="int" default="0" />

<ParamField path="output_schema" type="ListType | list[NameType]" default="[]" />

<ParamField path="processed_inputs" type="dict" default="{}" />

<ParamField path="processed_outputs" type="dict" default="{}" />

## `code_interpreter`

Execute Python code in a sandboxed environment with file I/O support. Supports spreadsheet analysis, data visualization, and generating artifacts. To read or edit uploaded files, pass them in the files input as an actual array of file references; those files are mounted at /work/inputs/\{filename} (curly braces shown for clarity; replace with the exact filename). Continued sessions restore prior inputs and generated files, so work can resume even if Python memory reset. Save output files to /work/outputs/ to have them collected as artifacts; call save\_file(...) for durable/versioned user-visible files. Example: files=\["\$history.69dd11a49033ae4d8e65ab33"] and pd.read\_csv('/work/inputs/data.csv'); plt.savefig('/work/outputs/chart.png'). You will see stdout and stderr outputs after each execution step. Include an existing session id to keep executing code within the same session.
